THE APPLICATION OF PROBLEM BASED LEARING BY USING LIVE WORKSHEET WEBSITE TO IMPROVE PROBLEM SOLVING SKILL IN LEARING QUADRATIC EQUATION IN CLASS IX STUDENTS OF SMPN 1 GALANG

This research was conducted to improve the problem solving skills of class IX-3 students of SMPN 1 Galang in learning mathematics with the topic of quadratic equations. Learning is carried out using Live Worksheets as learning media using the Problem Based Learning (PBL) method. The object of this
research is to improve problem solving skills in learning quadratic equations in student classes IX-3 SMPN 1 Galang in the academic year 20022/2023. This study used a classroom action research method that focused on Cycle I and Cycle II. In this study the instruments used were observation (students observation and teacher observation) and test (pre-test, post-test I and post-test II). Based on the data
that has been analyzed, it is obtained that the students' problem solving abilities have increased from cycle I to cycle II with a gain index of 0.56 in the "Medium" category. Therefore, the researcher concludes that applying the Problem Based Learning using the Live Worksheet website can improve problem solving skills in learning quadratic equations in class ix students of SMPN 1 Galang.
